l Be itknown that I, CHARLES OsTEma citi zen of the United States,residin at New Haven, in the county of New Haven and State ofConnecticut, have, invented anew and useful Improvement-in De'tachableHeels; ,and I do hereby declare the'follow ing, when taken-in connectionwith themcompanying drawings and the characters of reference markedthereon, to be a full, clear, and exact descriptionof the same, andwhich said drawings constitute part ofthis application, and represent,in

This invention relates to an improvement in detachable heels, andparticularly to means for securing the top lift in place, and

is adapted for use in connection with top plates formed from rubber,leather, metal or any other material, the object of the invention beinga simple arrangement of parts whereby top lifts may be readily securedto heels of boots and shoes and removed there from as occasion mayrequire; and the invention consists in the construction hereinafterdescribed and particularly recited in the claim.

In carrying out my invention I form the regular heel 11 with a recess 12in its under face, and in this recess I secure a heel plate 13preferably struck up from sheet metal and formed with a series oftransverse straps 1 1, 15 and 16 of different lengths and tapered attheir ends, the wider strap being near the forward end. These straps maybe struck out from the heel plate so as to be integral therewith, or maybe formed separately and attached 'to the plate. The plate is-alsoformed at its forward ed e with a clownwardly projecting flange 1 thecentralportion 18 of whichis cut away in line with'the strap 16 for thepurpose as will hereinafter appear. The flange is longer than the widthof the strap, and'the ends 19and 20 are turned inward. Preferably and asherein shown the inner end of the plate will be formed with a slightdepression 21 for the purpose as'h erein'after specified. In connec tionwith a heel thus provided with a heel plate,' I employa top lift 22which maybe formed from rubber, leather, wood or any other material.Secured to the upper face of the top lift 22 is a top lift plate 23corresponding in dimensions to the heel plate 13 and is formed withtransverse straps 24 and 25 respectively located so as to pass betweenthe straps l4 and 15 and the straps 15 and 16. These straps are ofdifferent lengths and tapered at their ends so that the straps on thetwo parts form a continuous taper. The top lift with its plate attachedis placed against the heel, and a key 26 inserted between the two platesso as to pass between the several straps thereon. This key is taperedcorresponding to the taper of the straps so as to firmly connect themtogether. This key is formed at its inner end with a slight recess 27 toengage with the projection 21 on the heel plate before referred to. Itis also formed near its outer end with a slight projection 28 which willengage with the edge of the flange 17 so that the key is locked inposition. The key is also formed with a downwardly projecting lip 29which closes the openings between the edge of the heel and the top liftand forms a finger-piece by which the key may be pried out as occasionmay require. Instead of forming the top lift from rubber, leather orsimilar material it may be formed from a sheet of metal 30, as shown inFig. 9 of the drawings, in which case the plate will be slightly largerthan the opening 12 in the heel so as to rest upon the edge of the heel,and this plate will be formed with downwardly projecting prongs 31 moreor less in number, which serve for use on icy walks. This metal platemay be readily removed when not required for use, and replaced byanother top lift. This construction permits the use of a top lift ofordinary construction; that is, for instance, a rubber heel having aflat upper face as it is only necessary to attach the top lift plate toa to enable at) be connected minimise,"

and so that after the heel is once prepared and provided with a heelplate, various top parts are not only firmly held in position,

but when occasion requires the key is more readily removed than might bethe case with a straight key if such a straight key should become rustyso' as to adhere to the straps. By forming-the straps as an-integralpartof the plates they have a certain amount of spring action so as toincrease the cushioned efi'ect of the heel. a

I claim i Means for attaching detachable heels com: prising a heel plateformed with a series of downwardly extending straps of different lengthsand tapered at their outer ends, said plate also formed at its forwardedge with a copiesof this patent may he obtained for portion of which ispartially cutaway, a top lift plate formed in" its upper face with adownwardly" projecting 'iiange, the 'central 7 series of straps ofdifierent lengths and V tapered at their ends and adapted to enter"between the straps on the heel plate, and a tapered key correspondingin width'to the distance between the inner walls of the ends of thestraps 'between which it is entered, said key formed with a downwardlyprojecting lip,and with a projection near its outer end to engage; withthe inner edge of the central portion of the flange on the heel plate.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses. l r r. y CHARLES OSTEN.
